Specification of Letters Patent.

Application filed August 2, 1913. Serial No. 782,552.

To all whom it may concern:

Be it known that I, FRANKLIN HARDINGE, a citizen of the United States,residing at Chicago,in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Machine-Benches, of which the following is a full, clear, concise, and exact description, reference being had to the accompanying drawings, forming a part of this specification.

My invention relates to machine shop equipment and is particularly concerned with a structural unit in the form of a bench upon which various machines and the driving means therefor may be mounted.

It is the object of my invention to provide a bench of the class pointed out which is of sturdy and substantial construction and in which the construction is such that the various stresses and strains, imposed by the arrangement and operation of the machines, may effectively be met.

The improvement of my invention, therefore, consists in the employment of bracing means comprising the combination of various supports, braces, struts and tie rods, which are all peculiarly disposed relative to the prime mover or the main shaft, the jack shafts'and the counter shafts.

It is a particular advantage of my invention that considerable bench room is provided with a minimum consumption of floor space and that, notwithstanding this economy, the parts are rigidly braced one against the other, for the proper mounting of the machines, and, at the same time, have the proper amount of elasticity to prolong the life of the structure.

My invention is illustrated in the accompanying drawings, in which- Figure 1 is a front elevational view of the machine bench of my invention; Fig. 2 is a side elevational view thereof; and Fig. 3 is a detail view of a brace which I employ.

It will be seen from the drawings that I provide a series of high uprights 4, 4, disposed in a row running lengthwise of the bench, and a similar series of high uprights 4, 4, running lengthwise of the bench and registering transversely with the firstuamed series. Each of these high uprights is screwed at the bottom into a supporting block 5, which is bolted to the floor by means of bolts 6, G, and each transverse pair of uprights is joined by three braces, 7 ,7 and 7 spaced along the length of these uprights as illustrated in Fig. 2. The braces 7, 7, 7 are preferably all alike and are illustrated in detail in Fig. 3, where it will be seen that each of them comprises a sleeve 8 snugly surrounding the upright 4 and a sleeve 8 snugly surrounding the upright 4. Each of these sleeves is firmly held upon its upright by means of set screws 9, 9, and the sleeves are joined by an integral web 10, preferably in the form of a T.

A supporting bracket 11 is mounted upon each of the high uprights 4, 4, at about table height, and is held in place by means of a set screw 12. A series of low uprights 13 extends lengthwise of the bench, in transverse alinement with the respective high uprights 4, 4, and a series of low uprights 13 extends lengthwise of the bench in transverse alinement with the respective high uprights 4, 4. Each of these uprights is screwed into a supporting block 14, which is secured to the floor by means of bolts 15 and at the top of each of the uprights 13, 13 is mounted a supporting bracket 16 in transverse alinement with the supporting bracket 11 on the corresponding high upright 4 or 4. A

transverse supporting bar .17 is rigidly blocks and supporting brackets between Cir lengthwise pairs of uprights, as illustrated in Fig. 1. These tie rods are all adjustable for the purpose of properly balancing and bracing the structure after it has been set up.

24 on a jack shaft 25 by twisted belt 26 Each of the jack shafts 2'5 and 25 are mounted in bearings carried upon an arm 27 which extends from a sleeve 28, surrounding and secured to the upright a or i, at the top, by means of set screws 29, 29. It is to be noted that the sleeves 28, 28 are mounted proximate to the brace 7 which has been described in. detail.

Mounted proximate to the brace 7 on each of the rods 4 and 4 is a sleeve 30, secured in place by means of set screws 31, 31, which sleeve carries an arm 32 having a bearing 33 at its end. A counter-shaft 34: is mounted in the bearings 33 and carries various apparatus 85, disposed wherever desired. At 36 and 37, I have shown some exemplary machines which are secured to the table 18 and which are operativcly connected with one or the other of the countershafts 8% through the medium of suitable belting as, 58.

Each of the braces illustrated in detail in Fig. 8 is provided with a pair of openings 39, 39 through which pipes or conduits 40 may extend. Such conduits are conveniently used for conveying the wires to an electric motor, for instance, or for the purposes of electric lighting, or to carry gas, or water, and these pipes are thus conveniently carried and are effectively put out of the way.

It will be seen that the entire structure is such that the bracing efiect is transmitted from the low uprights 18, to the high uprights 4, through the floor, table top, and the tie rods, then from the uprights i to the uprights 4?, through the braces, and then from the uprights 4 to the uprights 13 by way of the floor, the table top, and the tie rods. It will further be seen that the braces are disposed at the points whereby the strains due to the pull on the belt will be met most effectively and it will further be seen that the braces are adjustable so that the most advantageous point may be determined in each case. v

Obviously, many different kinds of machines may be used and may be variously disposed and the bolting and arrangement The shaft of countershafts and ack shafts will have to be particularly adapted in each instance. In any case, however, the bracing means is the same and the adjustability arranged for provides for the most effective bracing in each case.

I claim as new and desire to secure by Letters Patent:
